# Catalogs

Catalogs API allow brands to **Create**, **Update**, **Remove**, **List**, **View** and **Edit** catalog items, making it easy to maintain up-to-date content—like products, events, or offers—that can be dynamically injected into your campaigns or automations.

#### Rate Limiting

To ensure fair usage and platform stability, all Catalog API endpoints are subject to rate limiting.

**General Catalog API rate limit**

All Catalog API endpoints (including **Create**, **Update**, **Remove**, **View**, and **List**) are limited to **5 requests per second**. If the limit is exceeded, the API returns an HTTP `429 Too Many Requests` response. When this occurs, please wait a few seconds before retrying.

**Specific limit for /catalogs/items/edit**

The **/catalogs/items/edit** endpoint has additional operational limits due to its higher data throughput:

* Up to **5 requests per second**.
* Up to **1,000 items updated per second**.
* Each item in your payload counts as one update toward the limit.

If either threshold is exceeded, the API will respond with an HTTP `429 Too Many Requests` error.\
When that happens, slow down your requests or reduce the batch size to comply with the limit.
